Since then, it's been slow, and prompted me to look into this. Then to my even greater surprise, the PNY device transferred large files in minutes ONE time. To my great surprise, the Sandisk mentioned above did the same task in minutes. To add to the above I'm transferring large video files, and the very first time I used the PNY device it took 3+ hours to transfer 6GB.
Nevertheless, with the PNY device, when the transfer reports 5 hours to transfer 18GB of files and, it's actually faster for me to plug it into a late-2009 Mac Mini running El Capitan, that only has USB 2.0 ports, and then transfer them to my Macbook via a shared folder. Also, I can't find the model number on the drive, or a picture around the internet, but it's still at Best Buy, and it comes in the same packaging as this one: I haven't noticed any correlation yet between how fast it mounts and the transfer speed. With the PNY device, sometimes it takes close to 60 seconds for the device to mount (i.e., show up on the desktop), but most of the time it mounts quickly enough. I have a PNY 32GB USB 3.0 device that runs fast OCCASIONALLY, and a Sandisk SDCZ60-016G that usually runs fast.
I have the same problem with a new, mid-2015 Macbook Pro 15" running El Capitan. Any idea about the cloning issue? I am leaning towards Yosemite OS as the main culprint, since Maverick works OK, but want to get the expert opinion. Is the slow USB 3.0 speed a common problem or my MBP just have bad ports (both of them?)?Ģ). I tried both SuperDuper and Carbon Copy Cloner - same exact results. With Maverick, all the cloned image boot up fast and is usable, as if I the image is installed in the internal hard drive.
I can clone my new MBP with Yosemite as usual, but then booting up from the flash drive is SUPER SLOW, like this:
Version: 8.20 Serial Number: 000000000820Īnd this brings me to the next problem. 64 GB SanDisk UltraFit USB 3.0 ( 4 stars - 200 reviews )įrom the Amazon URL above, you'll see that o ther reviewers (see the Amazon URL) got 180 MBps Read and 80 Mbps Write, but I don't know if they are running Yosemite and/or the new MBPr.įrom the System Report, Yosemite show that these drives IS capable of USB 3.0 speed:.256 GB PNY USB 3.0 Turbo Flash Drive ( 4.5 stars - 1200 reviews in Amazon ).Tested with major flash drive proven to have high speed: I cannot get more than 40 MB Read / Write. Much better than Time Machine.Īnyways, I tried to do a CCC image on my MacBook Pro Retina 2014 with Yosemite and this is what I found out: So you can take the external drive, plug it is into any Mac, boot up and VOILA! You got your machine right there. For those who doesn't know, CCC can create a bootable image of your Mac. Cat-5e wiring is what you’ll find as much as the industry tries higher Cat-6 or 7 wiring and connectors are not being pulled.For all my previous MacBook (Air and Pro) with Maverick, I always backed it up using Carbon Copy Cloner (CCC). We’ve seen the same effect within Ethernet networking! As the data rate increased the need to switch out your wiring became a hardship for companies and people homes with in-wall wiring. Many people are still very glued to the older USB-A based devices and not likely to switch over anytime soon. As well as the waste of a still very useful device going into land fills! So consider what you have now that you’ll carry forward and the cost to replace them. Now let’s look at it from the other direction: Your older USB-A connecter devices will now need an adapter to connect to USB-C systems. To be clear you won’t get the higher throughput in older USB-2.x or USB-3.0 systems but you can start the process of switching over to newer devices like drives. As an example the Samsung T5 Ext SSD drive Note the Interface line: USB 3.1 Gen 2 (10Gbps), Backwards Compatibleīasically, the USB-C standard incorporates some of the signal lines for compatibility to the older USB 2.x/3.1 standards as they knew people needed this to move forward. With that said many USB-C devices do offer older USB connectivity.
Sadly your systems ports don’t offer USB-C abilities natively!
